N_K.  Tim wasn't very clear there.  

The error you are receiving is because you have to instatiate the workspace object first.  

Go to the VB Help and lookup "workspace" and also look up "opendatabase" using the Jet engine.

There are examples that are pretty clear on this subject.

but how to use the DSN in the connection string.
open method of the connection object.

Now that sounds much more like ADO than DAO, in ado all you do is:

Dim cnn As ADODB.Connection
Set cnn = New ADODB.Connection
cnn.ConnectionString = "DSN=MyDSN;"
cnn.Open

For a fuller DAO example:


   Dim wrkJet As Workspace
   Dim dbsMyDB As Database

   ' Create Microsoft Jet Workspace object.
   Set wrkJet = CreateWorkspace("", "admin", "", dbUseJet)

   MsgBox "Opening Database..."
   Set dbsMyDB = wrkJet.OpenDatabase("DSN=MyDSN", False,False)

Dear TimCottee
  will it work for the database in the network also????

Absolutely, the DSN specifies where the database is located.

TimCottee,

boss really a beautiful code but how to use the recordset object to open a table.
will you pls help us on this.

ADO or DAO?

ADO only.

ADO is easy:


Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Set cnn = New ADODB.Connection
Set rst = New ADODB.Recordset
cnn.ConnectionString = "DSN=MyDSN;"
cnn.Open
rst.Open "MyTable",cnn,adOpenStatic,adLockOptimistic,adCmdTable
With rst
  .MoveFirst
  Do
    Msgbox .Fields("MyField").Value
    .MoveNext
  Loop Until .Eof
End With
rst.Close
cnn.Close
Set rst = Nothing
Set cnn = Nothing

Dear Friends,
   in the connection object open method is it possible to use the dsn name instead of using file path for the access database using ado.
